摘要:
A method of fabricating a thyristor-based memory may include forming different opposite conductivity-type regions in silicon for defining a thyristor and an access device in series relationship. An activation anneal may activate dopants previously implanted for the different regions. A damaging implant of germanium or xenon or argon may be directed into select regions of the silicon including at least one p-n junction region for the access device and the thyristor. A re-crystallization anneal may then be performed to re-crystallize at least some of the damaged lattice structure resulting from the damaging implant. The re-crystallization anneal may use a temperature less than that of the previous activation anneal.

A service appliance is installed between production servers running service applications and service users. The production servers and their service applications provide services to the service users. In the event that a production server is unable to provide its service to users, the service appliance can transparently intervene to maintain service availability. To maintain transparency to service users and service applications, service users are located on a first network and production servers are located on a second network. The service appliance assumes the addresses of the service users on the second network and the addresses of the production servers on the first network. Thus, the service appliance obtains all network traffic sent between the production server and service users. While the service application is operating correctly, the service appliance forwards network traffic between the two networks using various network layers.

A high power rectifier device has an − drift layer on an N+ layer. A number of trench structures are recessed into the drift layer opposite the N+ layer; respective mesa regions separate each pair of trenches. Each trench structure includes oxide side-walls and an oxide bottom, and is filled with a conductive material. A metal layer contacts the trench structures and mesa regions, forming Schottky contacts at the metal-mesa interface. Shallow P regions extend from the bottom of each trench into the drift layer. Forward conduction occurs when the Schottky contact's barrier height is overcome. When reversed-biased, depletion regions form around the shallow P regions and the oxide side-walls which provide potential barriers across the mesa regions that shield the Schottky contacts from high electric fields, providing a high reverse blocking voltage and reducing reverse leakage current. The device's unipolar structure provides low switching losses, enabling high switching speeds while reducing the power that must be dissipated when transitioning from forward conduction to reverse blocking mode.

Provided are methods for the pretreatment of ligno-cellulosic biomass such as softwoods with bisulfite such as ammonium bisulfite without the need for exogenous acid. In one variation, a method of pretreating ligno-cellulosic biomass is provided including the following steps: a) providing ligno-cellulosic biomass; b) contacting the ligno-cellulosic biomass with a solution comprising bisulfite at an amount between 1 and 10% of a dry weight of the ligno-cellulosic biomass to form a slurry; c) heating the slurry to a first temperature of 150-210° C. for a first period of time to form a first mixture; d) cooling the first mixture to a second temperature of 100-200° C. to form a second mixture; and e) maintaining the second mixture at the second temperature for a second period of time to form pretreated ligno-cellulosic biomass; wherein the first temperature is higher than the second temperature.
摘要:
A service appliance is installed between production servers running service applications and service users. The production servers and their service applications provide services to the service users. The service appliance replicates the service data of service applications and monitors the service application. If the service appliance detects that the service application has failed or is about to fail, the service appliance takes control of the service. Using the replica of the service data, the service appliance responds to service users in essentially the same manner as a fully operational service application and production server and updates its replica of the service data as needed. When the service appliance detects that the service application has resumed functioning, the service appliance automatically synchronizes the data of the service application of the production server with the service appliance's data and returns control of the service to the service application and its production server.

A method for performing high-level synthesis (HLS) of a digital design includes a first phase for performing transformations on a behavioral description of the design, and a second phase for selecting a transformation from a plurality of transformations for transforming the behavioral description. The method further includes a third phase for implementing the transformed behavioral description using lower level primitives, and a fourth phase for generating implementation codes for the design.

A method for resizing the macro cells' boundaries of an integrated chip is disclosed and that becomes effectual after the initial floorplanning process has been completed. The method of the present invention apportions any excess area that is freed-up after the initial floorplanning process by altering the sizes or dimensions of the macro cell within the hierarchy of the integrated circuit in such a manner that the fractional change in the percentage occupancy is substantially constant among all macro cells at all hierarchy levels.
